The ODS format (OpenDocument Spreadsheet) is the default file type for spreadsheet applications like LibreOffice Calc and Apache OpenOffice. It's open-source, standards-based, and great for users who prefer free alternatives to Microsoft Excel.
However, ODS files can be inconvenient in mixed environments. Many businesses still rely on Microsoft Excel, which sometimes struggles with full ODS compatibility—especially when dealing with advanced formulas, macros, or formatting. Sharing ODS files with colleagues, clients, or systems that expect XLSX or CSV can lead to errors or formatting issues.
That's why users often convert ODS files into formats like XLSX, CSV, or PDF. Converting ensures smoother collaboration, easier integration with modern tools, and reliable presentation when sharing reports or finalized spreadsheets.
